Children who screen positive for amblyopia, reduced vision in one eye, before age 2 appear to have better visual outcomes than those whose vision problems are detected during screenings between ages 2 and 4. view more (2008-04-15)
Which came first: Primates' ability to see colorful food or see colorful sex?
The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists. view more (2007-06-27)
Serious vision problems in urban preschoolers rare but not that rare, Hopkins study shows
In what is believed to be the first comprehensive eye disease study among urban pre-schoolers, Johns Hopkins investigators report that while vision problems are rare, they are more common than once thought. Also, they say, a small group of children with easily treatable visions problems go untreated, while others get treatments they don't need. view more (2009-04-01)
Million pound study to help prevent blindness

Hopkins study shows 30-day soft contact lenses pose very small risk of vision loss
A team of researchers led by the Johns Hopkins Wilmer Eye Institute have determined that the corneal infection rate associated with the use of 30-day -extended-wear contact lenses made from silicone hydrogel is comparable to that previously reported for older lens types worn for fewer consecutive 24-hour periods. view more (2005-12-02)
